Evolutionary Genetics and Genomics

Our paper on speciation in stick insects made the cover of Nature Ecology and Evolution (image by Moritz Muschick). In this paper we show how multiple factors come together for speciation to move from early to late stages of isolation and genomic differentiation, and we identify a distinct gap in genomic differentiation between con- and hetero-specific populations in sympatry.

We recently published a paper in Molecular Ecology Resources describing a method to determine ploidy in mixed ploidy samples from low to modest coverage GBS-like data (paper). This relies on both estimates of heterozygosity and allele specific read depth. The method we describe is implemented in the R package, gbs2ploidy. You can read more about it in this informative blog from the Molecular Ecologist.
